Not at atmospheric pressure. You need at least 25 atmospheres pressure to solidify helium-4 and at least 29 atmospheres (0.3 K) for helium-3. See Wikipedia. At low pressure you fail to solidify the helium because of weak interatomic interactions combined with quantum mechanical zero point energy. Higher pressure favors forming a denser structure with an ...
