Deformed shell model results for two neutrino positron double beta decay of 84^{84}Sr

Half-lives $T_{1/2}^{2\nu}$ for two neutrino positron double beta decay modes $\beta^{+}$EC/ECEC are calculated for $^{84}$Sr, a nucleus of current experimental interest, within the framework of the deformed shell model based on Hartree-Fock states employing a modified Kuo interaction in ($^{2}p_{3/2}$, $^{1}f_{5/2}$, $^{2}p_{1/2}$, $^{1}g_{9/2}$) space. For a reasonable description of the spectra of $^{84}$Sr and $^{84}$Kr and to generate allowed GT strengths, the single particle energies of the proton and neutron $^1g_{9/2}$ orbitals, relative to the $^{2}p_{3/2}$ orbital energy, are chosen to be (3.5 MeV, 1.5 MeV) for both $^{84}$Sr and $^{84}$Rb and (1.5 MeV, 1.5 MeV) for $^{84}$Kr. With this, the calculated half-lives for the $\beta^+$EC and ECEC modes are $\sim 10^{26}$yr and $\sim 4 \times 10^{24}$yr respectively.Comment: 4 figures, re-orginized the previous version, accepted for poublication in International Journal of Modern Physics

Nonhost Resistance IN Arabidopsis Thaliana (Col-0,Ler-0,Npr,Pen2 Gfp) Against Magnaporthae Oryzae

Nonhost resistance is an expansive range plant protection that gives safety to all individuals from a plant animal types against all detaches of a microorganism that is pathogenic to other plant species. After arriving on the surface of a nonhost plant animal categories, a potential fungal pathogen at first experiences preformed and, later, activate plant safeguards. One of the introductory guard reactions from the plant is pathogen-related sub-atomic example (PAMP)-activated resistance (PTI). Nonhost plants likewise have components to distinguish nonhost-pathogen effectors and can trigger a barrier reaction alluded to as effector-activated invulnerability (ETI). This nonhost resistance reaction frequently brings about an excessively touchy reaction (HR) at the contamination site. This review gives a diagram of these plant safeguard methodologies. We count plant qualities that present nonhost resistance and the fungal counter-protection methods. Furthermore, prospects for utilization of nonhost imperviousness to accomplish expansive range and sturdy resistance in harvest plants

Shell model and deformed shell model spectroscopy of 62^{62}Ga

In the present work we have reported comprehensive analysis of recently available experimental data [H.M. David et al., Phys. Lett. B {\bf 726}, 665 (2013)] for high-spin states up to $17^+$ with $T=0$ in the odd-odd $N=Z$ nucleus $^{62}$Ga using shell model calculations within the full $f_{5/2}pg_{9/2}$ model space and deformed shell model based on Hartee-Fock intrinsic states in the same space. The calculations have been performed using jj44b effective interaction developed recently by B.A. Brown and A.F. Lisetskiy for this model space. The results obtained with the two models are similar and they are in reasonable agreement with experimental data. In addition to the $T=0$ and $T=1$ energy bands, band crossings and electromagnetic transition probabilities, we have also calculated the pairing energy in shell model and all these compare well with the available theoretical results.Comment: 9 pages, 4 figure
