Effect of an orientational phase transformation on low-temperature creep in n- H 2
The low-temperature stationary creep of solid normal hydrogen grown in a polycrystalline form is investigated. The experimental temperature range 1.4–4.2 K includes the temperature T c of the phase transformation of n- H 2 . It is found that as the temperature of n- H 2 decreases to T c the stationa...

| Zusammenfassung: | The low-temperature stationary creep of solid normal hydrogen grown in a polycrystalline form is investigated. The experimental temperature range 1.4–4.2 K includes the temperature
T
c
of the phase transformation of
n-
H
2
.
It is found that as the temperature of
n-
H
2
decreases to
T
c
the stationary creep rate of the samples abruptly decreases. This which could be due to stiffening of the
n-
H
2
lattice as a result of orientational ordering of the orthomolecules. |
