Complete set of polarization transfer coefficients for the reaction at 346 MeV and 0 degrees
We report measurements of the cross-section and a complete set of
polarization transfer coefficients for the reaction at a
bombarding energy = 346 MeV and a reaction angle =
.
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
, which are presumably the result of the three-proton =
3/2 resonance.
The spin--parity of the resonance is estimated to be , and the
distribution is consistent with previous results obtained for the same reaction
at = 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
