dc.description.abstractNH molecular radicals are magnetically trapped using helium buffer-gas loading at $\sim$600 mK. The helium collision Zeeman relaxation and energy transport cross sections are measured, and the ratio of these cross sections is $\sigma_{\mathrm{d}}/\sigma_{\mathrm{in}} = 7 \times 10^4$, sufficient for trap lifetimes of order 1 s. The scaling of the helium-induced Zeeman relaxation of $^3\Sigma$ molecules is investigated by changing the radical rotational constant through isotopic substitution. We also measure the spontaneous emission lifetime of NH($X$, $v=1$), providing a precision measurement of this transition strength for the astrophysical community.en_US
