The total cross section of the capture reaction n+p→d+ γ has been measured at E n =25 MeV using a hydrogen gas target and a scintillation counter telescope. The resulting value σ tot =(26.6+1.5) μ b is in line with other np-capture data in the energy region 14–72 MeV. The experimental data are compared with theoretical predictions.

Measurements of total cross sections for very slow neutrons with velocities from 100 m/sec to 5 m/sec

Inspire Record 1389650 DOI 10.17182/hepdata.28969

Very cold neutrons from 60 μeV to 0.1 μeV were obtained through a vertical total-reflecting neutron guide tube. Total cross sections measured by time-of-flight technique for gold and aluminium were found to obey the 1 ν law.

Inspire Record 1389657 DOI 10.17182/hepdata.29226

The processes K − d → Σ − p and K − d → Λn have been observed at K − momenta of 340 MeV/c and 400 MeV/c. The cross sections for these processes are: σ ( Σ − p) = 200 ± 30 μ b at 400 MeV/c, σ ( Λ n) = 200 ± 30 μ b at 400 MeV/c, σ ( Σ − p) = 300 ± 100 μ b at 340 MeV/c, σ ( Λ n) = 360 ± 150 μ b at 340 MeV/c.

Inspire Record 1389653 DOI 10.17182/hepdata.29197

In a study of K + p interactions at 12.7 GeV/ c we have carried out a search for meson resonances having any one of the following properties: (a) a strangeness of S =2, (b) S =1 and isotopic spin of I= 3 2 , or (c) S =1, I= 1 2 and decaying into an antihyperon ( Y ) and a nucleon (N).

Neutrons from the breakup of $^{19}$C

Marqués, F.M. ; Liegard, E. ; Orr, N.A. ; et al.

Phys.Lett.B 381 (1996) 407-412, 1996.

Inspire Record 1389647 DOI 10.17182/hepdata.55047

Neutrons arising from the breakup of a 30 MeV/nucleon 19 C beam on a tantalum target have been measured using the 98 element array DEMON. A narrow, forward peaked neutron angular distribution, with a corresponding momentum spread considerably smaller than those measured simultaneously for 21 N, 22 O and 24 F, was observed for charged fragments with Z < Z proj . Interpreted in terms of the core-breakup reaction model, the results support the existence of a one neutron halo in 19 C.

Total cross-section for n-p and n-d scattering at 10 GeV/c neutron momentum

Engler, J. ; Horn, K. ; König, J. ; et al.

Phys.Lett.B 27 (1968) 599-601, 1968.

Inspire Record 1389110 DOI 10.17182/hepdata.752

The total neutron cross-sections were measured with high precision for hydrogen and deuterium. At an average neutron momentum of 10 GeV/c we obtained σ T (np)=39.5±0.5 mb and σ T (nd)=73.3±1.1 mb. These values are in excellent agreement with p-p and p-d total cross sections. No energy dependence was found for n-p cross section between 4 and 10 GeV/c.
