In this paper we investigate the feasibility of Zeeman slowing calcium monofluoride molecules
originating from a cryogenic buffer gas cell. We measure the A^2Π1/2(v = 0, J = 1
2 ) − X^2Σ1/2
(v = 0, N = 1) hyperfine spectrum of CaF in the Paschen–Back regime and find excellent
agreement with theory. We then investigate the scattering rate of the molecules in a molecular
Zeeman slower by illuminating them with light from a 10 mW broad repumper and a 10 mW
multi-frequency slowing laser. By comparing our results to theory we can calculate the photon
scattering rate at higher powers, leading to a force profile for Zeeman slowing. We show results
from a simple 1D simulation demonstrating that this force is narrow enough in velocity space to
lead to significant velocity compression, and slowing of the molecules to trappable velocities.
