Complete set of polarization transfer coefficients for the 3He(p,n){}^{3}{\rm He}(p,n) reaction at 346 MeV and 0 degrees

We report measurements of the cross-section and a complete set of polarization transfer coefficients for the ${}^{3}{\rm He}(p,n)$ reaction at a bombarding energy $T_p$ = 346 MeV and a reaction angle $\theta_{\rm lab}$ = $0^{\circ}$. The data are compared with the corresponding free nucleon-nucleon values on the basis of the predominance of quasi-elastic scattering processes. Significant discrepancies have been observed in the polarization transfer $D_{LL}(0^{\circ})$, which are presumably the result of the three-proton $T$ = 3/2 resonance. The spin--parity of the resonance is estimated to be $1/2^-$, and the distribution is consistent with previous results obtained for the same reaction at $T_p$ = 48.8 MeV.Comment: 4 figures, Accepted for publication in Physical Review

Systematic measurement of

Space Star (SS) anomaly in Nd breakup cross section is well known. SS anomaly has large charge asymmetry; exp eriment is larger than calculation at nd SS and exp eriment is smaller than calculation at pd SS. There are also rep orts on anomaly in quasi-free scattering (QFS) cross section in Nd breakup reaction. At nd QFS, exp erimental cross section was found to be larger than calculation. On the contrary, pd QFS cross section measured by Köln group is smaller than pd calculation. We measured QFS cross section in pd breakup reaction, and compared the data with recent pd calculations to see angular dep endence of QFS anomaly

Measurement of

In our previous inclusive experiment on pd breakup at Ep = 247 MeV, we found experimental cross section is about twice larger than 3N calculation with ππ3NF at forward angle. Therefore we made exclusive measurement of 2H(p, p1 p2)n cross section at the same 247 MeV. Preliminary data indicate that the cross section enhancement appears at forward angles of θ1 and θ2. We made also inclusive experiment again and confirmed the previous data

Measurement of 2H(p, pp) n cross sections at Ep = 250 MeV

In our previous inclusive experiment on pd breakup at Ep = 247 MeV, we found experimental cross section is about twice larger than 3N calculation with ππ3NF at forward angle. Therefore we made exclusive measurement of 2H(p, p1 p2)n cross section at the same 247 MeV. Preliminary data indicate that the cross section enhancement appears at forward angles of θ1 and θ2. We made also inclusive experiment again and confirmed the previous data

A potentially common peptide target in secreted heat shock protein-90α for hypoxia-inducible factor-1α–positive tumors

ETOC: Deregulated/overexpressed HIF-1α is found in many solid tumors, and directly sabotaging it is challenging therapeutically. HIF-1α uses secreted Hsp90α, which uses a key epitope, F-5, for invasion and tumor formation. Drugs that target F-5 may be more effective and less toxic for treatment of HIF-1α–positive tumors
