Shape transitions far from stability: The nucleus 58Cr

Abstract Excited states up to I π = 8 + in the neutron-rich nucleus 58Cr have been identified by using a new experimental setup composed of the large acceptance magnetic spectrometer PRISMA and the highly efficient γ-detector array CLARA. Interestingly, the excitation energy sequence of the ground-state band follows the one expected by the E ( 5 ) dynamical symmetry for a nucleus at the critical point of the shape phase transition from a spherical vibrator ( U ( 5 ) ) to a γ-soft rotor ( O ( 6 ) ). For the first time, in the same physical system, large scale shell-model calculations in the full fp shell are compared to the E ( 5 ) analytical model results and to the Interacting Boson Model. The theoretical results are in excellent agreement with the present data

Proton-hole states in the N=30 neutron-rich isotope K49

Excited states in the N=30 neutron-rich isotope K49 have been studied using multinucleon transfer reactions with thin targets and the PRISMA-CLARA spectrometer combined with thick-target γ-coincidence data from Gammasphere. The d3/2 proton-hole state is located 92 keV above the s1/2 ground state, and the proton-particle f7/2 state is suggested at 2104 keV. Three other levels are established as involving the coupling to 2+ of two neutrons above the N=28 shell. The measured or estimated lifetimes served to reinforce the interpretation of the observed level structure, which is found to be in satisfactory agreement with shell-model calculations

Maternal psychological state and infant’s temperament at three months

Objective: The study aimed to investigate the possible relationship between maternal psychological state in the perinatal period and the child’s temperament at 3 months postpartum. Background: The perinatal period is a phase of intense psychological complexity which may increase the risk of the development, or a recurrence of psychological disturbances in parents. The current literature highlights the potential negative effects of a perturbed maternal psychological state on fetal and newborn development. Among the consequences of fetal exposure to maternal states of depression or anxiety are increased inconsolable crying and sleep disturbance in the newborn, difficult temperament, motor and cognitive development delays in children and a higher risk of depression in adolescence. Methods: A longitudinal design using self-report measures of maternal mood, and maternal report of the infant’s temperament, was used. The sample comprised 107 Italian, low-risk nulliparous women. Maternal and infant variables were assessed in the third trimester of pregnancy and at 3 months postpartum. The variables measured included: maternal depression, anxiety, prenatal attachment, alexithymia, social support, maternal bonding with parents, stressful events, and the infant’s temperament. Results: Higher scores of antenatal depression and postnatal state anxiety were independent predictors of increased temperamental difficulties of the baby. Conclusion: The results support the hypothesis that maternal perinatal states of depression or anxiety are associated with increased difficulty in the temperament of the baby as perceived by mothers. This therefore supports the need for prevention-treatment programmes from the early stages of pregnancy. © 2014, © 2014 Society for Reproductive and Infant Psychology

Maternity Social Support

Most literature suggests the importance of social support during the pregnancy. This research utilized the Spearman's rho coefficient, which was calculated between the Maternity Social Support Scale (MSSS) score and the Center for Epidemiologic Studies Depression Scale (CES-D) score, as well as Prenatal Attachment Inventory (PAI) score. The results confirm that during the pregnancy a high social support level is associated with a low depression level and a high social support level is associated with a high prenatal attachment level. Therefore, these results are significant, especially for maternity wellbeing promotion programmes
